Rumbling V8 engines, ground-pounding American muscle – these are the characteristics of Classic American Muscle cars, or as they are known in SCCA® Solo® – CAM cars.

These muscle cars which are so popular at the fancy auctions have also found a home in SCCA® fulfilling their purpose – getting them out of the garage and being pushed to their limits of something other than gathering dust.

SCCA has three classes for these types of cars – CAM C, CAM T and CAM S.

CAM T: In this case, the “T” stands for Traditional, and this class is for car and truck body styles originating from 1954-89. (Minimum weight w/o driver is 3000 lbs.)

CAM S: The “S” stands for Sports and this class is where sports cars, sedans/coupes, and trucks with seating for 2 or more adults. (Minimum weight for 1984+ Corvettes and Vipers is 2900 lbs. Minimum weight for all other cars is 2500 lbs.)

CAM Challenge events take place over the course of a weekend, with the first day set aside for class competition and an evening awards dinner. Winners in each class are determined by adding the best time of three morning runs added to the best time from three afternoon runs.

On Sunday, the event sets its sight on determining an overall event winner, and this is done through a qualifying round of three runs, then a series of elimination challenge rounds for the top 16 drivers in each class. For the qualifying drivers they will run straight up until a final three (one from each class) are determined, and then an equalization index (RTP/PAX) will be used to score the overall winner of the event.
